Pineapple weed, Matricaria matricarioides, relishes the challenge of rooting into a well-trodden path or other seemingly unhospitable soils. When walked on the plant's leaves release a pleasant pineapple-like scent, but a single plant will flower and produce thousands of plants in its short lifetime, quickly spreading through the garden.
Solution
Organic
Hand weed or hoe out seedlings as they appear, or smother them with a good layer of compost or mulch. Try to remove plants before they flower and seed to slow its spread.
Chemical
Use a total weedkiller, such as glyphosate. Avoid spraying on a windy day and near other desirable plants.
